I've been closely monitoring my raspberries this year because every year I get fairly major leaf damage. This year I am determined to beat whatever is eating them. I had assumed that the problem was spider mites. So I dutifully mulched and made sure they got lots of water (not hard since we've had a good amount of rain so far this spring).
But that hasn't seemed to have helped. I went out to check on them tonight and this is an example of what I found:
You can't quite tell from the picture but the damage is 'lace like'. For the most part there are no big chomps out of the leaves like caterpillar damage (which I'm used to - I had to squash countless caterpillars on my gooseberry bushes this weekend). I looked under a lot of the leaves and found some strange fly things that looked like baby mosquitoes. I also found one small brown beetle-like bug that the size of a large pin head.
Any suggestions on what it is or what I can do about it? It hasn't seemed to affect the plants much (they are spreading like crazy), but I think it is affecting my yield.
